T0 at whom it may concern.-

Be it known that I, GEORGE F. GODLEY, a citizen of the United States,residing at Philadelphia, in the county of Philadelphia and State ofPennsylvania, have invented certain new and useful Improvements inDust-Shields for Axle-Boxes; and I do hereby declare the following to bea full, clear, and exact description of theinvention, such as willenable others skilled in the art to which it appertains to make and usethe same.

My invention has relation to dustshields for car-axle boxes; and it hasfor its object a simple and durable dust-shield composed of asheet-metal plate snugly fitting the axle, and between which and therear wall of the axle-box is a packing-plate of a different material.

My invention accordingly consists of the combinations, constructions,and arrangements of parts, as hereinafter described in the specificationand pointed out in the claims.

Reference is had to the accompanying d rawin gs, wherein- Figure 1 isalongitudinal section of an axlebox, with part of the axle in elevation,having a dust-shield in section, embodying my improvements. Fig. 2 is anedge elevation of part of the dust-shield with clamping-ring therefor insection; and Fig. 3 is a face view of the same, showing the axle-journalin section.

A represents the usual or other form of axle-box, having in its rear endor wall the chamber a, which preferably has an open top a, as moreplainly indicated in Fig. l, to divide the rear end of the axle-box intofront and rear walls a and (t respectively.

The dust-shield B in chamber a consists, essentially, of a sheet-metalplate 0, preferably made of steel, having a central opening 0 snuglyfitting the axle, said central opening having, preferably, an outerflanged or upset edge a to provide a suitable bearingsnrface for theplate C on the axle to avoid cutting or wear of the latter by saidplate. Said plate 0 is located contiguous to the rear side of the frontwall a so that the flanged edge 0 of the opening 0 in said plate projects through the axle-opening in said wall a Between the plate 0 and therear wall a of box A in chamber a is a packing or plate D, of anysuitable materialsuch, for instance, as a plate of wood, a layer of redfiber, papiermacho, felt, or other analogous yielding or elasticmaterial-having a central opening d to fit the axle. I prefer, however,to make the packing or plate D in sections divided at the transversecenter line of the same with overlapping edges cl. (See more plainlyFig. These sections or the plate may be of a circular, oval, or othersuitable form and have grooved or recessed edges (1 for the reception ofa plain-wire or other suitablyconfigured spring d having free ends (1 dwhich abut against the sides of chamber a to prevent said plate orpacking rotating with the axle. If desired, however, said springwire maybe dispensed with.

The plate or packing D maintains the plate 0 in position to seal itagainst the rear face of the front Wall a to effectually exclude dustand prevent the escape of oil from box A.

From the foregoing it will be noted that the sheet-metal plate 0 has itscentral opening flange c integral therewith and directed to the frontwall a of chamber a, and that the elastic or yielding packing-plate D isbetween the plate 0 and the rear wall a and that said directed flange 0of plate 0 not only forms a bearing for the plate upon the axle, butalso returns any oil tending to escape from the box back to the latter.

I am aware that axle-box dust-shields composed of a metal and a packingplate are not new, and hence do not broadly claim the same, my inventionbeing limited to the specific constructions described and claimed.

This application is a division of another pending application, filed byme February 18, 1890, Serial No. 340,857.

W hat I claim is 1. In a car-axle box having a rear-wall chamber a,provided with an open top a, a metal dust-shield plate 0, having centralopening and adjoining the front wall a 'of chamber, and a packing-plateD, separate from plate 0, between the latter and the rear wall a ofchamber a, substantially as set forth.

2. In a ear-axle box having a rear-wall chamber a, provided with an opentop a, a dustshield plate 0, of sheet metal, having an upset edgecentral opening fitting the axle, and said edge flange being directedtoward the opening in the'front wall of chamber a, and 5 a packing-plateD, separate from the plate C;

joining the front wall of chamber a, and a packing-plate D, of adifferent material and separate from plate C, between the latter and therear wall of chamber a, substantially as 15 set forth.

chamber a, substantially as set forth.

3. In a oar-axle box having a rear-Wall chamher a, with open top a, asheet-metal dustro shield plate 0, having a flanged bore or centralopening and a fiangeless periphery adpresence of two witnesses.
